Application :filed April 8, 1914:. Serial No. 830,362.

To all LU/wm t may concern i .Be it known that l, KARL Soi-IEUERMANN,

a subject of the King of Prussia, German Emperor, residing at the cityof lWiesba-den, in the Kingdom of Prussia, Germany, have inventedcertain new and useful improve` ments in Drainage Plants for Road-Beds,of which the following` is a specification.

My invention relates to a drainage plant for roadbeds containingtramlines.

lt has been proposed to construct roadbeds containing 'tramlines, so asto quickly conduct the water off through passages beneath the paving, inorder to keep the rails and their bedding as dry as possible and toprotect them against destination by remaining water. rlhe known drainageplants for carrying oli' the water under the roadbed were not readilyaccessible and would easily become choked. he water had either to beconducted through very long conduits from the neighboring' soil, or thelatter very soon became non-absorbent in consequence of the impuritiesof the water. he surrounding of vthe rails had to be frequently torn upfor removing such chokings. For avoiding these difficulties the newplant is so ar ranged, that the waste and dirty water to be carried offis claried along its whole course and that these clarifying arrangementsare accessible along their whole length. rlhis affords the essentialadvantage that the ywater enters the adjoining soil in a perfectlyclarified condition, and that all choking and sanding of the soil is outof question. A further advantage is that by the constant control andcleaning of the clarifying arrangements these may always be kept intheir original condition. Furthermore the bedding carrying the rails ispreserved and the transection of the roadbed by pipes and the like isavoided. Lastly the noise produced by the traveling of the car isconsiderably reduced by the new arrangement.

The invention consists in constructing a drainage plant for roadbedscontaining tramway lines, by providing on the outsides of the railsbeneath the surface of the paving a series of hollow spaces which may beopened and in which the street waters run to the sides, and ooze away ina clarified condition after the solid parts have settled in removablesetting boxes.

In the accompanying drawings Figure l is the cross section through thetrack, bedding and one of the chambers. Fig. 2 is a, cross sectionthrough the track and the bedng at point between two such chambers. 3 isa cross section through the new plant, asphalt slabs being used betweentwo hollow chambers. Fig. 4L is a section between the tvo small canals.Fig. 5 is a longitudinal section parallel tothe rail and 6 is alongitudinal section through the plant according to Fig. 3. Fig. 7 is atop view of the whole plant.

a are the rails,which are bedded on the concrete bedding ZJ. On theoutside of each rail the concrete is made alternately in the form oftroughs and chambers, a trough always following a chamber. The troughshave grooves y, 2/ and the chambers have inclined bottoms o, o and areperforated in a checker-style.

The water Hows from the street directly into the chambers f, which areconnected by tie grooves y. ln the chambers it flows along the bottom o,is dammed up at the caps 72. ofthe clarifying pot i, and is here for thefirst time intensively clarified.` It then falls into the clarifying pote', when it is again clarified and passed asl cleaned water from theclarifying pots into the surrounding soil by which it is absorbed. Thedeeper chambers f are coveredy at the level of the troughs by perforatedplates w on which platesw wooden plugs g are fitted, which are beveledat their foot so that also here a system of hollow spaces is produced,which serves, together with the grooves y to assist the water in running0E. The plugs g are bored at a, and through these bores pipes o arepassed, which are connected to the cover plates fw of the chambers. lnthe pipes o are pieces of wood g.

e is a jointing layer for forming a close joint on the inner side of therail. It consists of an elastic, softer kind of asphalt and issufficient as a protection against the water penetrating inwardly.

el is the cover of the road which consists of asphalt or the like.

ln the shafts r of the chambers f are arranged the clarifying pots e'formed with overflow holes K arranged at the middle of their height andwith caps 7L with the entrance holes s.

With the newplant all water, which comes into the range of the rails,flows toward the chambers f, which is chiefly the object of the systemof grooves y. In the chambers f the Water Will dam up and thereby thesolid particles contained in it Will settle'from the liquid, and thethus preliminarily clarified Water passes through the holes s, s intothe clarifying pots i, rises in these and emerges through the holes Kinto the surrounding soil through the shafts as clarified Water. Throughthe pipes 0 probes may be introduced for ascertaining the amount of mudwhich has been deposited, and from time to time the chambers j may beopened by removing the plugs g and the cover plates w. ri`hen the Wholecourse of the Water is accessible, the bottoms o of the chambers may becleared of mud and the clarifying pots may be` removed and cleaned. TheWhole plant is thus kept in its original condition.

In the arrangement as shown in Figs. 3 and l asphalt plates are employedin place 'ofthe Wooden plugs g. I-Iere concrete slabs Z having 'groovesn are laid on the cover plates fw and over these concrete slabs theasphalt plates are laid.

The slabs Z are bordered by the steel plates '29. The clarifying potsare composed of three parts, namely the pot properl z', the inset i andthe cap or hood /L with its admission holes s.

I claim:

l. In a drainage plant for road-beds containing tracks, the combinationof chambers .having inclined bottoms and removable covers on the outsideof the rails and arranged beneath the surface of the road, and troughsin the bedding of the road on the outside of the rails, and opening intothe said chambers. i

2. In drainage plants for road-beds containing tracks, the combinationof chambers having inclined bottoms, clarifying pots-in the chambers andprovided with outf let holes in the middle of their side Walls,

and caps on said pots having inlet openings situated above the bottomsof the said charn-k bers.

In drainage plants for road-beds containing tracks, the combination ofchambers having removable cover plates beneath the road-bed, a removableWood paving supported by said plates, and troughs formed with groovesleading to the chambers.

In drainage plants for road-beds containing tracks, the combination ofchambers beneath the road-bed, removable, grooved cover plates over saidchambers, asphalt plates carried by said cover plates, and troughshaving small passages leading to said chambers.

6. In drainage plants for' roadbeds containing tracks, the combinationof chambers having removable covers beneath the roadbed, aclarifyingdevice in each chamber comprising a pot having outlet openingsin its side Walls above its bottom, an inset in said pot, and a cap onthepot having inlet openings above the bottom of the said chambers.

In testimony whereof I have aflixed my signature in presence of tvvoWitnesses.
